10.1.5 Monitor the Data Related to Torque Reference/Output Torque
 How to check the torque reference value and torque bias value during torque control?
 How to check the output torque?
Torque reference monitor [d009]
 Displays the torque reference value used for torque control.
 This monitor is enabled when "Permission of torque control [ATR] (52)" of the input terminal
function is turned on and is in the torque control state, and displays the torque equivalent to the
rated current of the inverter as 100%. For details, refer to "9.6.3 Driving by Torque Reference".

Output torque monitor [d012]
 In sensorless vector control, the estimated output torque during speed control/torque control is
displayed as 100% of the torque equivalent to the rated current of the inverter.
 In this monitor, powered is a positive value and regeneration is a negative value in forward
rotation, and powered is a negative value and regeneration is a positive value in reverse rotation.
For details, refer to "9.6.4 Driving with Torque Bias".
